  We basically run on tiny combustion engines. Exothermic reactions.

  We aren’t a passive 98 degrees, we would be hotter if it wasn’t cool enough outside. Higher heat would cause different cellular structures to become misshapen, leading to system breakdown. I’d be like trying to run a cpu cooling loop with boiling water.

    And I’d add to that that if our thermal dissipation is overwhelmed, our internal heat build up. To do that heat dissipation, we need to have an environment that suck out more heat out of us than what we produce. If the environment is too hot, the heat build up and as Deadrek says, our internal inner workings beak down.

    That why we sweat. Water suck out a lot more heat than air, because it wants to saturate the ambiante air, and to do that it suck up our body heat to become steam. Rince and repeat (literally).

    But once the air is to humid, it gets more and more difficult for our sweat to evaporate, which makes it ineffective. That why we can kinda survive in a 90°C + sauna (albeit not for long), but not in a 37°C (98°F) 100% humidity place like some tropical rainforest. At least, not without specialized acclimatation and survival techniques.

      There’s actually theoretically an endothermic reaction we do. E coli can undergo an endothermic reaction if it has enough zinc. It’s entirely possible this is why we have an appendix. I’ll link studies if anyone is interested

        Link it, I’m always up for some science.

  (that’s 23 and 37 degrees, for the rest of the world)

  Anything approaching equalizing of interior with exterior temperature results in heat-related illness.

    Giggles in heatstroke if you stay too long in a sauna

      Which is why you visit an avanto, a hole in the ice. To take a dip. Or roll in the snow. Cold shower will do in a pinch.

      Then rinse and repeat. Literally.

      Good for the circulation
